Thank you very much for providing the link.
I cried when I was watching 北航六十周年视频.
Besides its glory, 北航 has experienced 3 periods of hardship:
1. Its startup time (1952-->1956) --- when started from nothing;
2. The "cultural revolution" time (1966-->1976) --- when it stopped running as a true university;
3. The "军转民" time (1983-->1995) --- when it lost its Aerospace/Military focus. (视频 does not mention this event)
Nobody even mention how expensive the running cost has been especially in the time when most people in the nation were under starvation and poverty.
I believe 北航 has great potential and there are more glories yet to come.
